A week with classes, parties and rentals: a sample calendar

One gym, four kinds of booking, seven days. A sample week that puts classes, parties, rentals and open gym where each fits best, and the reasoning behind it.

Apr 21, 2026 · 5 min read

Most gyms add parties and rentals one request at a time. A parent asks about a Saturday party, so you squeeze one in at 11. A homeschool group wants the floor on Tuesdays, so they get 4 PM because it happened to be free that week. A year later the calendar is a patchwork, and your best hours belong to whoever asked first.

It works better the other way round: decide which kind of booking owns each part of the week, then fill it. Here's a sample week for a gymnastics club with one main gym (which splits into two halves with a curtain), a party room and a small upstairs studio. Swap in your own rooms; the reasoning holds for a cheer gym, a community centre or a dance studio with a party room. Spring is a good time to do it, before the fall schedule is set.

Who can come when

Start with the people, not the rooms. Every hour of your week suits someone:

• School-age children can come from 3:30 to 8 on weekdays, and on weekend mornings.
• Preschoolers and their parents are free on weekday mornings.
• Birthday parties happen when the guests' families are free: weekend afternoons.
• Adults and organized groups (a homeschool co-op, a daycare, an adult league, a cheer team without a gym of its own) come in the middle of the day and late in the evening.
• Families who want to play, not enroll, come when they have a free hour: Friday night, Sunday morning.

That list is most of the plan. Each kind of booking goes where its people are, and where it doesn't push out something that has nowhere else to go.

The sample week

Monday to Thursday

• 9:30 to 11:30: preschool classes in one half of the gym. Parent-and-tot at 9:30, three-to-fives at 10:30.
• 11:30 to 3:00: rentals and groups. A homeschool co-op's gym class on Tuesdays and Thursdays, a daycare visit on Wednesdays. The upstairs studio rents to a tutor or a fitness instructor.
• 3:45 to 7:30: recreational classes by age, both halves of the gym running at once.
• 5:00 to 9:00: team practice at the competitive end of the gym.
• 8:00 to 9:30: adult tumbling two nights, and a cheer team renting the floor the other two.

Friday

• Mornings as above.
• 4:00 to 6:00: classes.
• 6:30 to 9:00: a kids' night out or open gym, sold as drop-ins.

Saturday

• 8:30 to 12:30: classes on both halves of the floor, back to back.
• 12:30 to 1:00: nothing. This half-hour is on purpose.
• 1:00 to 5:30: three parties, each an hour in the gym, then 45 minutes in the party room.
• 6:30 to 9:30: an evening rental: a team, a youth group, a company's family night.

Sunday

• 10:00 to 12:00: open gym, capped at a number your coaches can watch.
• 12:30 to 5:00: three more parties.
• Evening: closed, or one regular renter who locks up.

Why the hours fall that way

Classes get first pick, because they repeat and they're picky. A class at 10 AM on Saturday earns that hour every week for the whole season. Say two classes run on the two halves of the floor, ten children each, on a $200 ten-week term: that's $20 a child a class, $400 for the hour, less two coaches. And a class for school-age children can only run in a handful of hours a week, so it needs those hours more than anything else does.

Parties go where classes don't. A $360 package for twelve children earns about what a class hour does, so this isn't about the money. It's about who else could use the hour. A party is just as happy at 1 PM, when classes are done and the coaches are still in the building. Put a party at 10 AM and the class it pushed out has nowhere to go.

The gym sets the pace on party afternoons. An hour of play and 15 minutes to reset the equipment means the gym is ready for a new party every 75 minutes. The party room needs 45 minutes and 15 to clear, so it's always ready in time. Start parties 75 minutes apart, at 1:00, 2:15 and 3:30, and each group leaves the gym just as the next one arrives.

Rentals fill what's left. A homeschool group at 1 PM on a Tuesday pays, say, $90 an hour for an hour you'd otherwise heat and light for nobody. That's less than a class or a party would earn, and that's fine: those hours were never going to hold either. The mistake is renting prime time. A league that wants Wednesday from 5 to 7 all season is taking two hours that could hold four classes. Say no, or quote it at what those classes would have earned. There's more on that in renters next to classes.

Open gym goes where the staff already are. On Friday evening and Sunday morning a coach or two is around anyway, and families who'd never commit to a term still come. It's also how many of the families who will enroll first find you.

The half-hour of nothing

The gap between Saturday's last class and the first party looks like waste. It isn't. Classes run over. Parents chat in the lobby. Children from the 11:30 class want to show their parents one more cartwheel. Without the gap, the first party's guests arrive into a crowd, the host can't set up, and the birthday child's parent has decided you're disorganized before the cake comes out.

The same goes for every change of use: from preschool to a homeschool group, from team practice to a renter. Give each change ten or fifteen minutes, and put that time on the calendar so nobody books into it.

Mistakes worth avoiding

• Saying yes to the first asker. A party at 11 because a parent asked nicely, a rental at 4 because it was free that week. Decide who owns each hour first, then say yes inside that.
• Open gym and a party on one floor at once. Unless the gym divides cleanly, the party's guests and the drop-ins end up mixed, and so does who's watching whom.
• A rental with a soft ending. An evening renter who stays until 10:15 means a staff member who stays until 10:30. Hold the room for their setup, and for putting it back after.
• Bookings in three places. If classes live in one system, parties in a notebook and rentals in an inbox, someone will double-book a Saturday. One calendar, everything on it.

Where Caletan fits

In Caletan, every kind of booking holds its rooms on one calendar. A party package books the gym and then the party room in order, with set-up and clear-up time held around each. A rental can't take a room a class holds, and half a gym is a room inside a room: rent one half, and the whole gym isn't offered. More for gymnastics clubs.
